Abstract: A checkout apparatus for barcodeless merchandise, the checkout apparatus includes an image camera module and a control module coupled to the image camera module. The image camera module obtains a merchandise image includes the barcodeless merchandise. The control module receives the merchandise image and generates an output datum according to a result of a merchandise identification program after the control module performs the merchandise identification program on the merchandise image. At least one of the image camera module and the control module is coupled to the point of sales (POS) management system or is embedded in the POS management system, the output datum is readable for the POS management system.

Abstract: The present disclosure provides a QR code graphic manufacturing device, which comprises a gray-scaled adjusting module, a data-hiding module, and an error-diffusion module. The gray-scaled adjusting module is used to adjust a gray-scaled value of an original image to generate a modified gray-scaled image. The data-hiding module and the error-diffusion module are respectively used to process the modified gray-scaled image and a QR code, and to generate a QR code graphic with a better hidden effect.

Abstract: A method of creating a graphic Quick Response (QR) code includes a picture and first and second two-dimensional barcodes combined through a halftoning technique. The graphic QR code includes a plurality of module units, each having a plurality of sub-modules. Information dots containing first information for the first two-dimensional barcode are provided, and each of the information dots of the first two-dimensional barcode is located at a central sub-module of each of the module units. The first information is readable by a scanning device. Information dots containing second information for the second two-dimensional barcode are provided, and each of the information dots of the second two-dimensional barcode is located at one of the other sub-modules. A position of each of the information dots of the second two-dimensional barcode is capable of being located by inputting a key through a decryption program for obtaining the second information.
